Innovation:

A flexible connector 3 is sealingly connected between the insertion end of the socket 22 and the opening end of the positioning plate 21 .

Specifically, the flexible connector is made of elastic material and has a stepped cylindrical shape. The diameter of the upper port of the flexible connector 3 is smaller than the diameter of the lower port. The upper end of the flexible connector 3 has a cylindrical first connecting portion 31 extending inward. The lower end of the flexible connecting member 3 has a flat ring-shaped second connecting portion 32 expanding outwards, the axis of the first connecting portion 31 and the axis of the second connecting portion 32 coincide.

The first connecting part 31 and the outer wall of the plug-in end of the socket 22 are sealed and connected by a vulcanization process, and the second connecting part 32 and the front wall of the opening end of the positioning plate 21 are sealed and connected by a vulcanization process to realize waterproofing.

The flexible connector 3 can reset the socket 22 after being subjected to an axial or radial force, and is used in conjunction with a limit mechanism to prevent the flexible connector 3 from excessive elastic deformation, thereby affecting its service life and improving its service life.

Reset principle:

1. The stepped cylindrical structure of the flexible connector 3 matches its own material characteristics, so that the socket 22 fixedly connected to it can automatically reset after being subjected to an axial force.

2. After the socket 22 and the flexible connector 3 are fixedly connected, the socket 22 is suspended in the cavity, and the axis of the socket 22 coincides with the axis of the first connecting part 31 and the axis of the second connecting part 32 . like Therefore, combined with the material characteristics of the flexible connecting member 3 itself, the socket 22 automatically resets after being subjected to a radial force.

Technical comparison:

In the floating connector proposed by the present invention, the socket 22 is reset after being subjected to an axial or radial force through the flexible connecting piece 3, and the elastic deformation of the flexible connecting piece 3 is controlled by the cooperation of the limit mechanism (it is also the floating amount of the socket 22). control).

Compared with floating connectors using springs, there is no rust problem, and the production and assembly costs are lower.

Compared with the floating connector with bellows structure, the traditional bellows structure itself determines that its fatigue resistance and reliability are insufficient, and it is prone to permanent deformation after use, which requires manual correction, otherwise the set of connectors will fail and be scrapped. The radial and axial swing/float ranges are not easy to control. However, the flexible connector 3 in the present invention has the function of resetting, and is used in combination with a limiter mechanism capable of controlling the amount of elastic deformation, so that the service life is prolonged.

Therefore, the present invention has the following advantages:

The floating connector proposed by the present invention has simple structure and low production cost, adopts a flexible connecting piece to cooperate with a limit mechanism, has stable connection and waterproof performance, and is suitable for popularization.
